Description

FIELD OF THE INVENTION

The present invention relates to antiperspirant deodorant cosmetic compositions with dermo-calming action for after-depilation sensitized skin, applicable in the cosmetic, hygiene and personal-care industry.

BACKGROUND OF THE INVENTION

Deodorants are intended for perfuming the body and, in general, they contain antimicrobial components, particularly antibacterial and antifungal, which eliminate bacteria and fungi that cause bad smell on the skin. Deodorants may be applied to armpits to perfume them and diminish the odors generated in this body region; however they do not prevent perspiration.

Antiperspirants have the function of controlling the perspiration by inhibiting or reducing it, thus guaranteeing protection against sweat, besides having antimicrobial action, eliminating the microorganisms that cause bad smell. The antiperspirant action is due to the fact that this product acts by forming a blocking film that prevent sweat from coming out, without causing damage to one's health.

It is known that depilation, be it by wax, laser or nippers, induces cutaneous irritation in determined persons and body regions.

Among the measures which one should take with depilation are: non-exposure to direct sunshine, skin cleaning, use of light and loose clothes, as well as attention to deodorants, creams and body oils used after the depilatory procedure. For this reason, care with the skin has become essential, although cutaneous irritations still occur, even with such care.

In this regard, the search for specific products for this purpose, particularly for deodorants that provide relief of irritation caused on the skin, i.e., sensitized by depilation, becomes critical. Also, in addition to deodorants that relieve irritation, it becomes essential to develop products that group deodorant characteristics to fight odor, antiperspirant for reducing sweat, and still that have a dermo-calming action on the skin.

A few examples of prior-art documents related to the area of the present invention, particularly antiperspirant deodorants, are presented hereinafter.

Patent application PI0924661-4, published on Nov. 21, 2012, in the name of Symrise AG, relates to ฯ‰-cycle-hexylalkan-1-ols, to the use of said compounds as antimicrobial agents for the treatment of odor on the body or for the preparation of an antimicrobial cosmetic or pharmaceutical formulation. Said PI0924661-4 further describes antimicrobial formulations containing, for instance, 2-methyl-cyclohexylpentanol. However, said document does not mention or suggest the use of said active or formulations thereof as antiperspirant deodorants with dermo-calming action, especially for after-depilation sensitized skin.

U.S. Pat. No. 8,115,033, published on Feb. 14, 2012, in the name of Symrise Ag relates to the chemical compound 3-(4-hydroxy-3-methoxyphenyl)-1-(4-hydroxyphenyl)-1-propanone, which is different from the chemical compound of the present invention called SymDeoยฎ B125: 2-methyl-5-cyclohexylpentanol. In the same way as the above-cited document, U.S. Pat. No. 8,115,033 does not mention or suggest the use of the active presently described and claimed or its formulations as antiperspirant deodorants with dermo-calming action, or use on after-depilation sensitized skin. In addition, even if this were the case, this is an active ingredient that is not foreseen in the composition of the present invention.

U.S. Pat. No. 6,172,016, published on Jan. 9, 2001, in the name of Bush Boakes Allen Inc., is directed to the use of pentane derivatives as cosmetic ingredients. The difference with respect to the chemical compounds SymDeo of the present invention lies in the carbon to which the methyl radical is attached, which is the third one in the American patent, namely: 3-methyl-5-cyclohexylpentanol. Again, this is a document that foresees a deodorant composition without the after-depilation calming benefit for sensitized skins.

Therefore, the need to develop antiperspirant deodorant formulations with dermo-calming action still remains, particularly for sensitized skins, which, in addition to the deodorant and antiperspirant properties, will exhibit emollient sensorial characteristics and a protective film, and provide dermo-calming action on the skin. Such need is fully met with the composition of the present invention.

SUMMARY OF THE INVENTION

The present invention relates to antiperspirant deodorant cosmetic compositions with dermo-calming action, which comprise as active ingredients, 2-methyl-5-cyclohexylpentanol and aluminum hydrochloride, as well as commercially acceptable adjuvants, directed to application in the cosmetic, hygiene and body-care industry.

The cosmetic composition of the present invention is prepared in a conventional way, known to those skilled in the art.

Tests:

Test 1โ€”Instrumental Evaluation of the Effect of the Composition of the Invention (Called 13-39540-03) on Erythema Caused by the Tape-Stripping Technique.

1.1โ€”Objective

Evaluating the potential of a calming action of a topical product referring to a composition according to the invention through instrumental measurements of colorimetry.

1.2 Methodology, Materials and Equipment

Two symmetrical 10 cm2 areas having randomized distribution in the front region of the forearms of the patients (a total of 21 participants) were demarcated. One of the areas was used for application of the product and the other was kept as control (untreated area). Colorimetric measurements were made with the equipment Mexameter MX18-Courge+Khazaka prior to tape-stripping removal (Fita Hipoalergรชnica TransproeMR) and application of the product (Tb) after 30 tape-stripping removals at each site (T0) and after 30 minutes, 1, 2, 3, 4, 5 and 6 hours from application of the product.

1.3โ€”Measurement of Erythema-Mexametry

The measurements were carried out by using the equipment Mexameter MX 18, Courage+Khazaka electronic GmbH through a measurement probe. The readings were made by applying the probe to the test areas with the pressure permitted by the spring (0.5 N).

The measurement area was 5 mm in diameter. Three measurements were carried out in each area. The measurement consisted in measuring the light absorbed and reflected at the wavelengths for green and red for hemoglobin and wavelengths for green and near infrared for melanin.

The operator positioned the probe vertically, forming a 90-degree angle with the skin and cleaned the probe with the aid of a very soft piece of paper prior to the first reading and between the readings of one area an another, even if it were the control area or the initial measurement of each area.

The reading indicated the degree of erythema of the skin. The scale of the equipment is arbitrary, the reading values indicating greater redness of the skin (erythema).

1.4โ€”Steps of Research

1.4.1โ€”First Step

    • The participants remained at rest in an air-conditioned room with temperature of 20ยฑ2ยฐ C. and relative humidity of 50ยฑ5% for at least 30 minutes prior to each reading;
    • The participants were told not to smoke; not to come out of the test room without prior authorization of the expert; not to come into contact with the area being tested at any place; not to contact the area being tested in contact with the clothes between the first air-conditioning and the end of the measurements; not to make abrupt movements with any part of the body; and not to allow the test area to get wet
    • The participants were evaluated by the dermatologist to confirm the research inclusion criteria;
    • Two symmetric 10 cm2 areas of the region before the forearms having randomized distribution were demarcated. One area was used for application of the product and the other area was kept as negative control (untreated area); and
    • One determined the coloration of the areas through arithmetic mean of three measurements (Tb).

1.4.2โ€”Second Step

    • 30 tape-stripping removals were carried out in the two demarcated areas. The adhesive tapes (TransporeMR) were replaced at each removal; and
    • One determined the coloration of the demarcated areas through the arithmetic mean of three measurements (T0).

1.4.3โ€”Third Step

    • The tested product was applied in a randomized manner, in the amount of 0.02 g in the demarcated region of each participant. The product was spread over the skin with the aid of a latex fingerstall, with light and circular movements until the whole application area was entirely covered and homogeneous. The latex fingerstall was changed in each area;
    • The measurements were carried out in the following times:
    • T30minโ€”thirty minutes after application of the product
    • T1hโ€”one hour after application of the product
    • T2hโ€”two hours after application of the product
    • T3hโ€”three hours after application of the product;
    • T4hโ€”four hours after application of the product;
    • T5hโ€”five hours after application of the product;
    • T6hโ€”six hours after application of the product.
    • The participants were evaluated by the dermatologist at the end of the measurements T6h; and
    • After the medical evaluation the participants were released.

1.5โ€”Statistical Analysis

For a statistical analysis of the results, different tests were employed, as follows:

In order to compare the treatments in each time, one used ANOVA, followed by the DUNNET test and to compare the times with regard to the initial time T0, one used the Student test t.

As said before, the number of participants of the research was 21 and all of them completed the study in question.

The trust level considered in the comparative analyses was of 96%.

1.7โ€”Conclusion

After the statistical analysis of the results, one can conclude that the composition of the invention promoted reduction of the erythema caused by the tape-stripping technique until the time of 4 hours.

Test 2โ€”Instrumental Evaluation of the Effect of the Composition of the Invention (Called 13-29540-04) on the Erythema Caused by the Tape-Stripping Technique

2.1โ€”Objective

Evaluating the potential of calming action of a topical product referring to a composition according to the invention through instrumental colorimetric measurement.

2.2โ€”Methodology, Materials and Equipment

Two symmetric 10 cm2 areas of randomized distribution in the region before the forearms of the participants (a total of 21 participants) were demarcated. One of the areas was used for application of the product and the other was kept as control (untreated area). Colorimetric measurements were made with the equipment Mexameter MX18-Courage+Khazaka before tape-stripping removal (Fita Hipoalergรชn TransporeMR) and application of the product (Tb), after the 30 tape-stripping removals at each site (T0) and after 30 minutes, 1, 2, 3, 4, 5 and 6 hours of application of the product.

2.3โ€”Measurement of Erythema-Mexametry

The measurements were carried out by using the equipment Mexameter MX 18, Courage+Khazaka electronic GmbH through a measurement probe. The readings were made by applying the probe to the test areas with the pressure permitted by the spring (0.5 N).

The measurement area was 5 mm in diameter. Three measurements were carried out in each area. The measurement consisted in measuring the light absorbed and reflected at the wavelengths for green and red for hemoglobin and wavelengths for green and near infrared for melanin.

The operator positioned the probe vertically, forming a 90-degree angle with the skin and cleaned the probe with the aid of a very soft piece of paper prior to the first reading and between the readings of one area an another, even if it were the control area or the initial measurement of each area.

The reading indicated the degree of erythema of the skin. The scale of the equipment is arbitrary, the reading values indicating greater redness of the skin (erythema).

2.4โ€”Steps of Research

2.4.1โ€”First Step

    • The participants remained at rest in an air-conditioned room with temperature of 20ยฑ2ยฐ C. and relative humidity of 50ยฑ5% for at least 30 minutes prior to each reading;
    • The participants were told not to smoke; not to come out of the test room without prior authorization of the expert; not to come into contact with the area being tested at any place; not to contact the area being tested in contact with the clothes between the first air-conditioning and the end of the measurements; not to make abrupt movements with any part of the body; and not to allow the test area to get wet
    • The participants were evaluated by the dermatologist to confirm the research inclusion criteria;
    • Two symmetric 10 cm2 areas of the region before the forearms having randomized distribution were demarcated. One area was used for application of the product and the other area was kept as negative control (untreated area); and
    • One determined the coloration of the areas through arithmetic mean of three measurements (Tb).

2.4.2โ€”Second Step

    • 30 tape-stripping removals were carried out in the two demarcated areas. The adhesive tapes (TransporeMR) were replaced at each removal; and
    • One determined the coloration of the demarcated areas through the arithmetic mean of three measurements (T0).

2.4.3โ€”Third Step

    • The tested product was applied in a randomized manner, in the amount of 0.02 g in the demarcated region of each participant. The product was spread over the skin with the aid of a latex fingerstall, with light and circular movements until the whole application area was entirely covered and homogeneous. The latex fingerstall was changed in each area;
    • The measurements were carried out in the following times:
    • T30minโ€”thirty minutes after application of the product
    • T1hโ€”one hour after application of the product
    • T2hโ€”two hours after application of the product
    • T3hโ€”three hours after application of the product;
    • T4hโ€”four hours after application of the product;
    • T5hโ€”five hours after application of the product;
    • T6hโ€”six hours after application of the product.
    • The participants were evaluated by the dermatologist at the end of the measurements T6h; and
    • After the medical evaluation the participants were released.

2.5โ€”Statistical Analysis

For a statistical analysis of the results, different tests were employed, as follows:

In order to compare the treatments in each time, one used ANOVA, followed by the DUNNET test and to compare the times with regard to the initial time T0, one used the Student test t.

As said before, the number of participants of the research was 21 and all of them completed the study in question.

The trust level considered in the comparative analyses was of 96%.

2.7โ€”Conclusion

After a statistic analysis of the results, one can conclude that the composition of the invention promoted reduction of the erythema caused by the tape-stripping technique until the time of 1 hour.

Test 3โ€”Instrumental Evaluation of the Effect of the Composition of the Invention (Called 13-39540-01) on the Erythema Caused by the Tape-Stripping Technique

3.1โ€”Objective

Evaluating the potential of a calming action of a topical product referring to a composition according to the invention through instrumental measurements of colorimetry.

3.2โ€”Methodology. Materials and Equipment

Two symmetrical 10 cm2 areas having randomized distribution in the front region of the forearms of the patients (a total of 21 participants) were demarcated. One of the areas was used for application of the product and the other was kept as control (untreated area). Colorimetric measurements were made with the equipment Mexameter MX18-Couage+Khazaka prior to tape-stripping removal (Fita Hipoalergรชnica TransproeMR) and application of the product (Tb) after 30 tape-stripping removals at each site (T0) and after 30 minutes, 1, 2, 3, 4, 5 and 6 hours from application of the product.

3.3โ€”Measurement of Erythema-Mexametry

The measurements were carried out by using the equipment Mexameter MX 18, Courage+Khazaka electronic GmbH through a measurement probe. The readings were made by applying the probe to the test areas with the pressure permitted by the spring (0.5 N).

The measurement area was 5 mm in diameter. Three measurements were carried out in each area. The measurement consisted in measuring the light absorbed and reflected at the wavelengths for green and red for hemoglobin and wavelengths for green and near infrared for melanin.

The operator positioned the probe vertically, forming a 90-degree angle with the skin and cleaned the probe with the aid of a very soft piece of paper prior to the first reading and between the readings of one area an another, even if it were the control area or the initial measurement of each area.

The reading indicated the degree of erythema of the skin. The scale of the equipment is arbitrary, the reading values indicating greater redness of the skin (erythema).

3.4โ€”Steps of Research

3.4.1โ€”First Step

    • The participants remained at rest in an air-conditioned room with temperature of 20ยฑ2ยฐ C. and relative humidity of 50ยฑ5% for at least 30 minutes prior to each reading;
    • The participants were told not to smoke; not to come out of the test room without prior authorization of the expert; not to come into contact with the area being tested at any place; not to contact the area being tested in contact with the clothes between the first air-conditioning and the end of the measurements; not to make abrupt movements with any part of the body; and not to allow the test area to get wet
    • The participants were evaluated by the dermatologist to confirm the research inclusion criteria;
    • Two symmetric 10 cm2 areas of the region before the forearms having randomized distribution were demarcated. One area was used for application of the product and the other area was kept as negative control (untreated area); and
    • One determined the coloration of the areas through arithmetic mean of three measurements (Tb).

3.4.2โ€”Second Step

    • 30 tape-stripping removals were carried out in the two demarcated areas. The adhesive tapes (TransporeMR) were replaced at each removal; and
    • One determined the coloration of the demarcated areas through the arithmetic mean of three measurements (T0).

3.4.3โ€”Third Step

    • The tested product was applied in a randomized manner, in the amount of 0.02 g in the demarcated region of each participant. The product was spread over the skin with the aid of a latex fingerstall, with light and circular movements until the whole application area was entirely covered and homogeneous. The latex fingerstall was changed in each area;
    • The measurements were carried out in the following times:
    • T30minโ€”thirty minutes after application of the product
    • T1hโ€”one hour after application of the product
    • T2hโ€”two hours after application of the product
    • T3hโ€”three hours after application of the product;
    • T4hโ€”four hours after application of the product;
    • T5hโ€”five hours after application of the product;
    • T6hโ€”six hours after application of the product.
    • The participants were evaluated by the dermatologist at the end of the measurements T6h; and
    • After the medical evaluation the participants were released.

3.5โ€”Statistical Analysis

For a statistical analysis of the results, different tests were employed, as follows:

In order to compare the treatments in each time, one used ANOVA, followed by the DUNNET test and to compare the times with regard to the initial time T0, one used the Student test t.

As said before, the number of participants of the research was 21 and all of them completed the study in question.

The trust level considered in the comparative analyses was of 96%.

6.5โ€”Conclusion

    • After a statistical analysis of the results, one can conclude that the composition of the invention promoted reduction of the erythema caused by the tape-stripping technique until the time of 1 hour and in the time of 5 hours.

Test 5โ€”Evaluation of the Reduction of Erythema Caused by the Tape-Stripping Technique by Using the Composition of the Invention (called NT1123-12-A).

5.1 Objective

Evaluating the efficacy of the topical product (called BDP 1160.18704.6) referring to a composition according to the in reducing skin erythema induced by mechanical insult and evaluated as a function of the redness of the skin. Ion this study, one evaluated the efficacy of a composition according to the invention (NT1123-12-A) in reducing cutaneous erythema with respect to a control (site without application of any products). The evaluations were carried in the following times:

t0: right after formation of the erythema induced by the tape-stripping method;

t0.5: 30 minutes after induction of the erythema and application or non-application of the product;

t1: 1 hour after induction of the erythema and application or non-application of the product;

t2: 2 hours after induction of the erythema and application or non-application of the product;

t3: 3 hours after induction of the erythema and application or non-application of the product;

t4: 4 hours after induction of the erythema and application or non-application of the product;

t5: 5 hours after induction of the erythema and application or non-application of the product.

5.2โ€”Methodology, Materials and Equipment

On each voluntary woman (a total of 25 participants), two 2.5ร—4.0 cm rectangles were marked with a surgical pen, called sites, on the left or right forearm. After 30 minutes of air-conditioning, the environment controlled at 20ยฑยฐ C. and 50ยฑ5% of relative humidity of the air, 30 tape-stripping removals with Transporeยฎ 3M tape were carried out at each site, followed by the measurements of erythema by the mexametry and colorimetry technique. These measurements were called basal measurements (t0). After the mechanical insult, the product was applied, and the voluntary women remained at the laboratory for the measurements after 0.5 (30 minutes), 1, 2, 3, 4, 5 and 6 hours. During the whole experiment the climatic conditions were kept constant according to the ranges cited before. At the site intended for the product, 80 ฮผL of the sample under study was applied, one of the sites being used as control (without application of any products).

5.3โ€”Acquisition of Measurements

The measurements were made by using a Mexameterยฎ MX 18 probe, coupled to the equipment Multi Probe Adapter MPA-5 (CKeletronics, Germany). Concomitantly with the measurements, one used an automatized spreadsheet of the software Microsoftยฎ Office Excel 2010 for calculation of the Variation Coefficient (VC/CV) of the readings obtained. One carried out 5 measurements per site in each time. If in 5 measurements the VC/CV presented a value lower than 4%, one would finish the measurements at the site and continue them in the next one; otherwise, the process was restarted by using the colorimeter Byk-Gardner Spectro-Guide Sphere Gloss. For this evaluation, one recorded only the values of a*, which is the axis that ranges from green (โˆ’120) to read (+120). The values were recorded on an automatized spreadsheet of the software Microsoftยฎ Office Excel 2010 for calculation of the Coefficient of Variation (CV/VC) of the readings obtained. One carried out 3 measurements per site in each time. If in 3 measurements the CV/VC presented a value lower than 4%, one would finish the measurements at the site and continue the measurements at the next one; otherwise the process was restarted until a CV/VC lower than 4% would be obtained.

5.4โ€”Results

5.4.1โ€”Evaluation of the Reduction of the Erythema by Mexametry

In evaluating of the reduction of the erythema by mexametry, one measured the erythema values (E) for each voluntary woman, at the site intended for the product and at the control site. FIG. 13 shows the average values of Erythema (E) obtained for the product site and control site.

In order to evaluate the homogeneity of t erythema caused by the mechanical insult, the values of erythema measured at each site in the basal time (t0) were statistically compared with each other by using the t-Student test, in pairs, with trust interval of 95%. The result is summarized in Table 27.

TABLE 27
Comparison of the values of erythema induced
after mechanical insult - Value of P.
Et0 product vs. Et0 control 0.5533 (non-significant)

According to the results obtained, there was no statistically significant difference between the sites (P>0.05), indicating the homogeneity in the values of erythema after the mechanical insult. This indicated that the study was conducted with homogeneous basal values of erythema at the evaluation sites.

In order to evaluate whether there were significant variations in the erythema along the study, the erythema measurements obtained after 0.5; 1; 2; 3; 4; 5 and 6 hours from application of the product, or the basal measurements (t0) were not compared, carried out right after the mechanical insult (prior to application of the product), by using the single-factor variance analysis method, with Dunnett post-test multiple comparison, considering ฮฑ=0.05. The results of the statistical analysis are summarized in Table 28.

Et0 vs. Et5 P < 0.05 (significant) P < 0.05 (significant)
Et0 vs. Et6 P < 0.05 (significant) P < 0.05 (significant)

According to the results, it was possible to find out that there was a statistically significant reduction (P<0.05) of the skin erythema after 0.5, 1, 2, 3, 4, 5 and h hours from application of the composition according to the invention as compared with the initial erythema (t0) and still that at the control site (without application of any products) was also obtained one observed a significant reduction (P<0.05) in the erythema formed by the mechanical insult after 0.5, 1, 2, 3, 4, 5 and 6 hours.

Although one has observed a reduction of the erythema at both sites along the study, it is possible to observe, in FIG. 14, which shows the percentage of Reduction of the Erythema (% RE) obtained in each evaluation time, what there was a more marked reduction of the erythema at the site intended for the product.

In order to evaluate the significance of the reduction of the erythema along the time, that is, the Calming Effect (EC/CE) provided by the product with respect to the control, one calculated the ratio between the erythema measurements after 0.5, 1, 2, 3, 4, 5 and 6 hours with respect to the value obtained right after the mechanical insult (t0), by using Equation 1.

The reduction of the skin erythema provided by the composition of the invention presented a statistically significant difference (P<0.05) after 30 minutes and 1 hour from application as compared with the respective control (site without application of any products). This indicated that the product was effective in reducing skin erythema by mechanical insult and evaluated as a function of the redness of the skin until 1 hour after application.

5.4.2โ€”Evaluation of the Reduction of the Erythema by Colorimetry

In evaluating the reduction of the erythema by colorimetry, one measured the values of the coordinate *a for each volunteer at the site intended for the product and at the control site. FIG. 15 shows the average value of the Erythema Intensity (+a*).

In order to evaluate the homogeneity of the erythema formed by the mechanical insult, the values of a* measured at each site in the basal time (t0) were statistically compared by using the t-Student test, in pairs, with trust interval of 95%. The results achieved are summarized in table 30.

According to the results obtained, there was no statistically significant difference between the sites (P>0.05), indicating that there was homogeneity in the values of a* after the mechanical insult. This indicated that the study was conducted with homogeneous basal erythema values for the sites under evaluation.

In order to evaluate whether there were significant alterations in the erythema along the study, the erythema measurements obtained after 0.5, 1, 2, 3, 4, 5, and 6 hours from application of the product or non-application were compared with the basal measurements (t0) carried out right after the mechanical insult (prior to application of the product), by using the single-factor variance analysis, with post-test of Dunnett multiple comparison, considering ฮฑ=0.0.05. The results of the statistical analysis are summarized in Table 31.

According to the results, it was possible to observe that that was a statistically significant reduction (P<0.05) of the skin erythema after 0.5, 1, 2, 3, 4, 5, and 6 hours from application of the composition according to the invention as compared with the initial erythema (t0), and that in the control site (without application of any products) there was a significant reduction (P<0.05) in the erythema formed by the mechanical insult after 0.5, 1, 2, 3, 45, and 6 hours. Although there has been a reduction of the erythema at both sites along the study, it is possible to observe, in FIG. 16, which shows the percentage of Reduction of Erythema Intensity (% RIE) obtained in each evaluation time, that there was a greater reduction of the erythema at the site intended for the product.

In order to evaluate the Calming Effect (CE/EC), one calculated the ratio between the measurements of a* after 0.5, 1, 2, 3, 4, 5, and 6 hours with respect to the value obtained along the mechanical insult (t0), by using Equation 2.

Test 6โ€”Instrumental Test of the Effect of the Composition of the Invention (Called 12-33171-07) on the Erythema Caused by the Tape-Stripping Technique

6.1โ€”Objective

Evaluating the potential of calming action of a topical product referring to a composition according to the invention through instrumental measurements of colorimetry.

6.2โ€”Methodology. Materials and Equipment

Two symmetrical 10 cm2 areas having randomized distribution in the front region of the forearms of the patients (a total of 19 participants) were demarcated. One of the areas was used for application of the product and the other was kept as control (untreated area). Colorimetric measurements were made with the equipment Mexameter MX18-Courage+Khazaka prior to tape-stripping removal (Fita Hipoalergรชnica TransproeMR) and application of the product (Tb) after 30 tape-stripping removals at each site (T0) and after 30 minutes, 1, 2, 3, 4, 5 and 6 hours from application of the product.

6.3โ€”Measurement of Erythema-Mexametry

The measurements were carried out by using the equipment Mexameter MX 18, Courage+Khazaka electronic GmbH through a measurement probe. The readings were made by applying the probe to the test areas with the pressure permitted by the spring (0.5 N).

The measurement area was 5 mm in diameter. Three measurements were carried out in each area. The measurement consisted in measuring the light absorbed and reflected at the wavelengths for green and red for hemoglobin and wavelengths for green and near infrared for melanin.

The operator positioned the probe vertically, forming a 90-degree angle with the skin and cleaned the probe with the aid of a very soft piece of paper prior to the first reading and between the readings of one area an another, even if it were the control area or the initial measurement of each area.

The reading indicated the degree of erythema of the skin. The scale of the equipment is arbitrary, the reading values indicating greater redness of the skin (erythema).

6.4โ€”Steps of Research

6.4.1โ€”First Step

    • The participants remained at rest in an air-conditioned room with temperature of 20ยฑ2ยฐ C. and relative humidity of 50ยฑ5% for at least 30 minutes prior to each reading;
    • The participants were told not to smoke; not to come out of the test room without prior authorization of the expert; not to come into contact with the area being tested at any place; not to contact the area being tested in contact with the clothes between the first air-conditioning and the end of the measurements; not to make abrupt movements with any part of the body; and not to allow the test area to get wet
    • The participants were evaluated by the dermatologist to confirm the research inclusion criteria;
    • Two symmetric 10 cm2 areas of the region before the forearms having randomized distribution were demarcated. One area was used for application of the product and the other area was kept as negative control (untreated area); and
    • One determined the coloration of the areas through arithmetic mean of three measurements (Tb).

6.4.2โ€”Second Step

    • 30 tape-stripping removals were carried out in the two demarcated areas. The adhesive tapes (TransporeMR) were replaced at each removal; and
    • One determined the coloration of the demarcated areas through the arithmetic mean of three measurements (T0).

6.4.3โ€”Third Step

    • The tested product was applied in a randomized manner, in the amount of 0.02 g in the demarcated region of each participant. The product was spread over the skin with the aid of a latex fingerstall, with light and circular movements until the whole application area was entirely covered and homogeneous. The latex fingerstall was changed in each area;
    • The measurements were carried out in the following times:
    • T30minโ€”thirty minutes after application of the product
    • T1hโ€”one hour after application of the product
    • T2hโ€”two hours after application of the product
    • T3hโ€”three hours after application of the product;
    • T4hโ€”four hours after application of the product;
    • T5hโ€”five hours after application of the product;
    • T6hโ€”six hours after application of the product.
    • The participants were evaluated by the dermatologist at the end of the measurements T6h; and
    • After the medical evaluation the participants were released.

6.5โ€”Statistical Analysis

The software used in the analyses was MINITAB 14 AND XLSTAT 2012.

As said before, the number of participants in the research was 19

The trust level considered in the comparative analysis was of 95%.
